Passing Parameters make other parameters drop

I am making a C# Razor MVC web app which uses kendo UI charts. I have 2 different chart setups on my index view.

3 of my charts pass a single parameter to a function called _GetAttrTop3 which then passes more parameters on to the controller. My 2 other charts don't send a parameter, but fires a function called _GetAttr() which sends parameters to the controller.

The problem is with the 3 charts that pass the parameter to the _GetAttrTop3 function. The parameter that gets passed to the function always gets passed along to the controller but there is always another parameter in that function that gets dropped.

Originally "Shift" was the parameter that wasn't passing, so I made it a session variable to fix the problem, but "Type" stopped getting passed, and now "LineName" isnt passing. So it seems that it always drops one parameter when I try to send it a parameter from one of the 3 WasteCategory#Charts. This is strange because the 2 other charts that dont send a parameter to their respective return function ( _GetAttr() ) work just fine.

attached is my _Layout.cshtml and my view called Index.cshtml

Letters for numbers

My customer, a bank, is used to (and it looks like it is a common behaviour) let users insert some special characters, in numeric boxes, to simplify and speed up typeing.
Notably, the use 'k' for 1.000, and 'm' for 1.000.000: so, to insert for example 1500000, the user can type '1.5m', obtaining the same result (and with minor chance of error).
Can I implement anything like that, in the NumericTextBox?
Thanks as always
Andrea

Cascading ComboBox Persistencecy with AJAX data binding passing selected value (MVC4)

I wanted some persistence with Cascading Combo Boxes when using an AJAX data binding.
The solution also needed to be able to pass a 'selected value from the controller handling the data retrieval.

This is what i came up with, hopefully this is useful to someone else aswell
cshtml
Only thing of note here is the jQuery DataBound event that will handle getting the selected value and setting it

<label for="Client">Client</label>

@(Html.Kendo().ComboBox()

.Name("Client")

.Placeholder("Select Client...")

.DataTextField("ClientName")

.DataValueField("ClientID")

.Events(e => e.DataBound("onDataBoundClient"))

.DataSource(source =>

{

source.Read(read =>

{

read.Action("GetClientsCombo", "Tools");

});

})

)

<label for="Package">Package</label>

@(Html.Kendo().ComboBox()

.Name("Package")

.Placeholder("Select Package...")

.DataTextField("PackageName")

.DataValueField("PackageID")

.Events(e => e.DataBound("onDataBoundPackage"))

.DataSource(source =>

{

source.Read(read =>

{

read.Action("GetPackagesCombo", "Tools")

.Data("filterPackages");

})

.ServerFiltering(true);

})

.Enable(false)

.AutoBind(false)

.CascadeFrom("Client")

)

ToolsController.cs
Additional bool coloumn in select that will return true only if selected Client/Package Id is = to session var

public JsonResult GetClientsCombo()

{

int selectedClientId = Session["selectedClientId"];

var query = //Linq Query to get results

select new

{

ClientID = LinqClientIdColumn,

ClientName = LinqClientNameColumn,

Selected = LinqClientIdColumn == selectedClientId

};

return Json(query, JsonRequestBehavior.AllowGet);

}

public JsonResult GetPackagesCombo(int clients, string packageFilter)

{

int selectedPackageId = Session["selectedPackageId"];

var query = //Linq Query to get results

select new

{

PackageID = LinqPackageIdColumn,

PackageName = LinqPackageNameColumn,

Selected = LinqPackageIdColumn == selectedPackageId

};

return Json(query, JsonRequestBehavior.AllowGet);

}

JS ondatabound events
These functions are called when data is bound to the combo boxes. They get the data object from the AJAX call and return an array of objects, using jQuery Grep, where selected is === true then use the first object found to populate select a default value from the combo.

I initially tried compacting these two functions into one abstracted function and passing the jquery selector reference and selectedObject[].property as variables in the event handler. Evidently passing variable eg (.Events(e => e.DataBound("onDataBoundPackage('var1', 'var2')")) in the databound event handler breaks the databinding.

function onDataBoundClient() {

var DataObject = $("#Client").data("kendoComboBox").dataSource.data();

var selectedObject = $.grep(DataObject, function (obj) {

return obj.Selected === true;

});

$("#Client").data('kendoComboBox').value(selectedObject[0].ClientID);

};

function onDataBoundPackage() {

var DataObject = $("#Package").data("kendoComboBox").dataSource.data();

var selectedObject = $.grep(DataObject, function (obj) {

return obj.Selected === true;

});

$("#Package").data('kendoComboBox').value(selectedObject[0].PackageID);

};

Drag and Drop bug - Exists since atleats 2012.1.515

I have two JS fiddles:

http://jsfiddle.net/fL28r/1/ - Using 2011.3.1129
http://jsfiddle.net/fL28r/2/ - Using 2012.1.515

First Fiddle:
If you try to drag and drop from the Grid to the treeView, you will see that the cursor offset looks valid and the row is not below the cursor.

Second Fiddle:
If you try to drag and drop from the GridView to the treeView, you will see that the hint gets displayed UNDERNEATH the cursor. This is causing me problems as it seems to think that the dropTarget is the hint object instead of a treeNode.

I have also tried this in the latest commercial build (v2012.1.601 [using my commercial account]) and am able to reproduce the issue. Would I be able to get help in resolving this issue?

OData Service: Invalid slug header for attachment.

I am trying to upload a file via a service that implements OData. I cannot seem to set any additional headers on the upload control. I need to set a custom slug header.

Here is the error I am receiving. Despite what it says the header format is below the error.

Invalid slug header for attachment. Slug headers must be of the form "EntitySet,ItemId,Name".

Here is how the headers should look:
Slug: MyListTitle|1|mydocument.docx

Resetting the scroller after a back button

We want to reset the scroller in the data-after-show function of a view. It works well everywhere except after a getting to a page using the back-button - as it seems that when we get there the app view id is still the one of the page where the button was clicked, and not the page to which we return and where the event is bound.

Is there a way around this?
